Abstract
Description
- None.
- None.
- None.
- This invention relates to surgical instruments for laser ablation procedures. More particularly, the invention relates to a sterile, disposable tip apparatus for such surgical instruments.
- Medical laser treatment using hand-held instruments has generally been developed for ophthalmic, dental, orthopedic, and similar surgical procedures where the treatment area is confined or particularly difficult to reach. Typically, laser light is transmitted from a laser source though an optical fiber to a treatment site. The optical fiber terminates proximally in a laser source connector for connection to the laser source and terminates distally in a handpiece manipulated by the surgeon.
- A handpiece used during one procedure cannot be used with another patient in a subsequent procedure unless some form of sterilization is performed. Types of sterilization techniques range from autoclaves to gas. Gas procedures are time consuming and costly. Autoclave temperatures generally have proven too severe for laser surgical handpieces to withstand.
- Accordingly it would be useful to provide a sterile, disposable tip for use with a laser surgical device.
- It would be of further use if the sterile, disposable tip provided means for precise alignment of the optical fiber in the tip to the source of laser energy in the surgical device.
- Yet another useful advantage would be for the sterile, disposable tip to be releasably attached to the device with precise optical, mechanical, magnetic, electromechanical, or electromagnetic locking and alignment assembly.
- Other features, advantages, and objects of the present invention will become apparent with reference to the following description and accompanying drawings.
